PAINTING-MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 425,547, dated April 15, 1890.

Application filed March 1, 1889. Serial No. 301,659. (No model.)

To all whom it may concern.-

Be it known that I, SEYMOUR W. PERE-VY GRINE, of Grand Rapids, in the county of Kent and State of Michigan, have invented a new and useful Improvement in Painting- Machines; and I do hereby declare that the following is a full, clear, and exact description of the same.

The object of my invention is to produce an apparatus for staining the ends of slats composing the backs and seats of schoolseats. It being desirable to provide a machine capable of adjustment, whereby alternate slats may be painted or stained to suit different widths of slats, I employ a series of laterally-adjustable pads, surfaces, orbrushes, which may be fixed in position in line with the slats desired to be painted after the manner shown in my application filed April 10, 1888, No. 270,214.

My invention consists of a table for supporting the school seat or back and a series of staining surfaces, brushes, or pads arranged in direct line with the edge of said seat or back, whereby the edges or ends of the slats will be stained when the seat and staining devices are made to abut against each other.

It consists, further, of a table for receiving the seat or back, a series of staining devices arranged in line with the edge of said seat or back, and a guide against which the seat or back abuts to accurately determine its position in relation to the staining devices.

It consists, further, of a series of pads on movable supports and a tank, the said supports being arranged to immerse the pads in the staining material when moved.

It consists, also, of a movable support for the staining devices combined with means for operating said support to and from the slat, whereby the slat ends and staining dc-- vices are caused to abut.

It consists, further, of a table, of a series of movable supports, each support carrying one or more staining dcvices,which may bebrou ght into line with the ends of the slats by movement of said movable supports, and as said pads may vary in size and configuration to suit different sizes and shapes of slats-that is, their cross-section configuration- -the ma chine is rendered capable by ad ustment of staining seats or backs in which the slats vary in size or shape.

The special form of pad, the details of construction, and the means of adjustment also form part of my invention.

In the drawings, Figure 1 is a side view of the table with the staining devices supported thereby and the seat ready to be moved against them, showing also one manner of arranging the tank. Fig. 2 is a detail perspective View of one end of the table with the staining devices, showing the construction which enables the table to be adjusted for different lengths. Fig. 3 is a detail view of a portion of the table with ,a modified arrangement of table and staining devices, illustrating also diiferent means by which the machine may be adapted to different lengths ofseats and backs, and means for moving the pads against the seat. Fig. 4; is a modified form of staining device adapted more especially to slats which are not connected by tongues and grooves, or, in other words, which have plain edges. Fig, 5 is a detail view of a modification.

In the drawings, 6 represents the supporting-table, having a set of staining devices B B at each end thereof. The seat C is placed upon the table between the two sets of staining devices, and by moving it first one way and then the other the end edges of the seat are forced against the staining devices and the ends of the slats stained according to position of the staining devices in relation to said slats, which, as in Fig. 1, will stain each alternate slat. The table is made in two parts, which parts are connected by slotted bars 1 2 and suitable holding-scre'vvs, which connection allows the table ends to be adjusted and fixed in position at greater or less distances apart, to suit different lengths of seats or backs.

The staining devices, preferably pads A, are carried upon movable supports, which, as shown, consist of cylinders or drums c, and these in turn are carried by shafts e, journaled in the hearings on the table 6. Then the slats to be stained are connected by tongues and grooves, the pads are of corresponding shape, those for the outside slats being plain on one edge and having a projection or notch on the other end to correspond with the tongue or groove of the slat, and those for the inside slats being formed with a notch on one side to correspond with the groove of the slat and a projection on the other side to correspond with the tongue, as at C6. The shafts upon which the movable supports are fixed extend transversely of the table, and openings are formed in the table beneath the supports to permit their partial movement and also permit the tanks which hold the staining material to be properly positioned in relation to said supports.

The preferred arrangement of tanks is shown in Fig. 1, located in the openings in the table beneath the movable supports, so that as the shafts are turned the staining-pads would be caused to pass into the staining material and be made ready to act upon any slats of the school-seats. The staining-pads,

as before stated, are positioned upon their: several supports substantially in line with.

each other, and where the seat is curved they arearranged in corresponding manner to be in line with the slats desired to be painted,

so that as the seat is moved forward it strikes 1 fairly against the pads, and by reason of the shape and size of said pads corresponding exactly to the ends of the slats the stain will be applied only to the desired slats, without touching upon those adjacent thereto. The movable supports are splined to the shafts, so as to have lateral movement, and are provided with grooved bosses on one side, as at 5, which receive the forked ends of the levers 6, held in the brackets 8. Bymeans of these levers the supports may be adjusted laterally to bring the pads into line with any desired slats. The seat is guided in its movement along the table to the pads by means of an adjustable strip 10, fixed to the table.

The shaft is turned by means of a treadle and strap 6 f, the latter of which passes about the pulley g on the end of the shaft. For returning the shaft after it has been moved in one direction, I provide a spiral spring 0, secured to the bracket and to one of the movable supports. The rotary movement of the movable supports is limited, so that the pads will stand in line with the edge of the seat, and this stoppage of the movement is secured by means of an adjustable stop as, which arrests the movable supports as the spring draws them back and raises the pads from the staining material. For securing accuracy in guiding the seat and in making the pads register exactly with the slats, I employ arms wt, supported on the shaft and extending low the guide-arms n movement therein. The pressure upon the treadle being relieved, the spring rotates the drums in the opposite di-' rection until contact is made with the adj ustable stop, at which time the movement will be arrested and the pads be in line with the slat ends, and then by moving the seat or back along the table its edge will pass beneath the guide-arms n, which will insure theaccurate guidance and registering of the slat ends with the pads. The adjustable stop-arm rests upon a spring-cushion y, and thus when the seat and pads are made to abut and the arms 01. bear upon the seat the said springcushion exerts a slight yielding pressure to .hold the arms firmly in place. 'VVhen it is desired to bring another set of staining de vices into action,it is necessary to adjust the operating strap and spring. The arms extend forward and have upturnedends adapted to bear upon the surface of the seat, and thus determine more accurately the position at which the pads stand in line with-the .end of the slat.

In Fig. 3 I show a modified arrangement of tank and pad. In this case the pad is held by a supplemental tank or pot D, which is secured to a drum E or similar movable sup-' port carried by the shaft 6. Several series of these supplemental tanks or pots carrying staining-brushes may be employed, as at 00' Fig. 3, to suit the slats of different shapes and sizes. Each staining-pot is provided with.

a nipple adapted to receive a tube '5, extend IOO ing from a main stain-tank F, supported above the table in a suitable position. tubes are provided with suitable cut-ofi valves, and when these are open the staining material passes from the main tank into the supplemental tank or pot and is absorbed The by the staining pads or brushes, which are 1 then ready to receive the thrust of the school seat or back. Arms h are used in this modification, as in that previously described, to make the pad register with the slat ends. The

drums maybe turned and fixed in position to bring any series of staining-pads of different sizes and shape into alignment with the slats, in which case,.of course, the tubes must be changed from one set of devices to the other.

The table is formed with an opening to receive the movable supports. The supporting-shaft is journaled in boxes 12 at the rear endsof the sliding plate 13. This plate slides in ways formed in the table, and has screws by which it may be fixed in a position to locate the two sets of staining devices at the table ends any desired distance apart to suit different lengths of slats. In this figure, also, I illustratemeans bywhich the staining devices may be moved against and away fromthe seat,which may be held stationary, and this method of operation is preferred by me to that previously described, in which the seat is moved against the, staining-pads. This means consists of the lever 1a, rock-shaft 15, the arm 16, and the rod 17, connected to the plate 13. By

moving the lever the shaft is rocked and the plate 13 moved to thrust the pads against the seat, the screws moving in the ways and allowing this action. The tubes i are of course made sufficiently long to permit this movement. I do not confine the application of these means to the particular arrangement illustrated in Fig. 3, it being shown in that construction merely for convenience, as itis obvious that the shaft shown in Fig. 1 may be mounted in a sliding plate, as 13, having connection to an operating-lever. It will be understood, also, that the means shown in Fig. 1 for adjusting the devices toward and from each other, consisting of the slotted bars 1 2, are intended for use with the arrangement shown in Fig. 8.

In Fi 5 is shown a modificatiomin which supporting-arms, as M, are employed, instead of the rollers, and in this instance the pads are removably held by a set-screw :0 which, when loosened, allows the pad to be withdrawn and a fresh one of different shape and size inserted.

In Fig. 4 I have shown means for staining the slats especially adapted to a seat composed of slats having plain edges or without any tongues or grooves. These consist simply of a belt of width equal to the width of the slat to be painted, a pair of rollers for supporting said belt in a vertical position or across the line of movement of the seat, and of a suitable staining-tank in which one of the rollers is located, in order that the staining material will be applied to the belt.
